lIPO'JYABI'I? CONCRETE-MOLD.

To all whom it may concern.'

Be it known that I, ORVILLE D. BARTow, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented 'new and useful Improvements in Portable Concrete-Molds, of which the following is a specification.

'tion and theke,

The invention relates to molds and 'more particularly to molds for concrete construcandl has for an object to provide a m'old for building walls and abutments or the like of concrete or some other cementitiou's. materials.

Among other features the invention comprehends a mold, preferably formed in parts so arranged and associatedfthat one will depend upon the other to insure a rapid andl eicient wall structure. To this end the parts or mold sections canbe readily as- `seinbled and as easilyv andgquickly separated, .thus not only affording a. convenient means for finishing the face or faces of the structure but also permitting -of the {inishingoperation on one part o-f the structure while the other" part is still in course of ,y erection.

T fragmentary perspective viewshowing vStill further objects and uses of the linvention reside in a mold, which provides a support for a scaffold, adapted to thev convenience and safety of the persons who pour or otherwise placethe cement in the mold.

A. still further object of the invention is the provision of a mold o-f this character which is extremel simple in construction, portable, strong, urable,reliable and elfi.-

.cient its purpose, and inexpensive-in manufacture.

With these and other objects in view, the invention consists in the construction, combination. and arrangement of parts as will be hereinafter fully described, illustrated in `'the accompanying drawing, and pointed out 'in theclaims hereunto appended.

i In the drawing the igure representsha t e the wallinrthe course of construction mo'id constructed in accordance with the invention applied.

-Referring to the drawing irril detail, A designates a base or foundation slab,pref erably made from concrete, cement or the like, and from which rises the wall i3, preferably made from concrete, cement or the like. At the inner side of the face Aof .the wall are arranged spaced parallel vertical Specitatioiil of Letters liatent.A

place,

studs 5, to which are secured sheathing strips 6, on the inner face of which are secured spaced vertical strips 7 forming air Connected to these strips 7 is the lathing 8 carrying the plaster 9 inthe ordinary well-known manner. To each vertical stud 5 are secured the floor joists 10, the

spaces.

f sheathing 6 being designed to serve as one r Wall for the mold hereinafter fully described;

The mold comprises a plurality of sections C,l only two of the same being shown in the drawing, and each includes a plu# rality of interfitted tongue and groove boards 11 securedto brace rails 12 which are formed with correspondingly beveled ends 13 so that on the stacking of the sections C the rails. 12 will overlap eachother at their beveled-ends on the respective sections -to closely and strongly t' the saine to ether.

most board 11 and at opposite sides of the intermediate rails 12 and on the inner side of each outermost rail are holding pins 14,

about which are adapted to be twisted the ends of anchoring wires 15 which arev trained about the alternate studs 5. These wires 15 however .are initially twisted around the rails 12 and are only untwistedl from the rails and twisted` arund the pins` tion without disturbing the position ofthe next superposed section.4 Thus when several of the sections C rare fitted with relationto each other, as shownin the view in the '14 when it is desired to remove a lower sec.

drawin the wires15 are first trained about the rai s 12 and have their ends twisted together to firmly secure the said sections in while later ywhen a' section is removed the'wires are fastened to the pins 14 for holding a section in position and preventing the dropping or lowering thereof, and

which would ordinarily occur' when'a'seeFV tion is removed if the` wires were not arranged as mentioned.

Adapted to be anchored in the ground spaced from the wall of the building during the course of erection thereof is a scaffold 16,

to each vertical member of which is fixed a cross stud 17 having at` one end a depending 'block 18 for'engagement with a longitudinal bar 19 fixed to the rails 12of each section C,

so that the mold, formed of the sections and. component parts lwill in fact act as a su ion iio

port or frame for the scaffold structure, t e

latter being rovided to assist the wormen in 1,placing t e concrete.

ounted in the studs and projecting from opposite sides thereof are spikes or `pins .20-which are adapted to become embedded inthe cement, concrete, or the like, to hold the same in position when it becomes hardened.

Fixed to the boards `11 and projected from the faces next to the cement, concrete, or the like, from which the wall is made, are a plurality of marking strips 21 which are adapted to form grooves in the outer face :of the concrete, cement, or the like to give the appearance thereto, as being made from tiles or blocks, these strips yto extend vertically horizontally or in any desired di# rection. l

llt will be particularly noted that the wires 15 occur in the lines of the marking strips and that the former are adapted to be cut o" `inside, of the face of the wall, the

marking strips and resulting grooves being also provided to hide the joints which would lainly show in instances Where the concrete v 1s poured at different times. To this end the grooves can be suitably filled with a finish or other mixture of concrete, and the facings 'of the mold painted or otherwise marked toshow where the 4joints will occur.

What is claimed is 1. In a concrete mold, the combination with spaced vertically disposed studs, of a pluralitybf false-work forms, each including interfltted tongued and grooved boards and transverse beams secured to said boards, Y

.said beams being correspondingly beveled at 'opposite ends, whereby, on stacking the forms one above the-other, adjacent ends of the beams will overlap eachY other, tie wires embracin certain of the studs and also embracing tlxe overlapped beveled end of the beam to hold the forms in spaced-relation to the studs for the molding of concrete, and pins mountedin thel forms near the lower edges thereof and adapted to be engaged by j certain tie .Wires- 'to hold the forms against lowering movement. 4
